A system includes a series of converters provided along a boundary of an agricultural cultivated area. A converter is configured to emit a second signal in response to an incoming first signal. The system also includes an autonomously driving agricultural machine including a transmitting device configured to emit the first signal in an environment of the agricultural machine, a receiving device configured to receive the second signal emitted in response to the first signal, and a processing device configured to determine a position of the agricultural machine with respect to the boundary based on the received second signal. An arrangement and/or a conversion characteristic of converters is designed differently at a first section of the boundary than at a second section of the boundary.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The system according to claim 1, wherein the conversion characteristic relates to the strength of the second signal in relation to the first signal.
3. The system according to claim 2, wherein the conversion characteristic depends on a type of the first signal.
4. The system according to claim 1, wherein the arrangement relates to a distance of a converter from an adjacent converter.
5. The system according to claim 1, wherein the arrangement relates to a vertical height of a converter.
6. The system according to claim 1, wherein a plurality of converters are arranged to be vertically offset at at least one location along the boundary.
7. The system according to claim 1, wherein both signals include electromagnetic waves corresponding to one another, and the converter is designed as a reflector.
8. The system according to claim 1, wherein both signals include different electromagnetic waves, and the converter is designed as a transponder.
11. An agricultural machine, comprising a control device according to claim 10, wherein the agricultural machine is configured to determine an impending crossing of the boundary based on its determined position.
